No. 16/573,783, filed Sep. 17, 2019, and entitled “SESSION MAPPING IN 5G AND SUBSEQUENT GENERATION NETWORKS,” the entirety of which priority application is hereby incorporated by reference herein.

TECHNICAL FIELD

The subject application is related to wireless communications systems in general, and to fifth generation (5G) and subsequent generation cellular communications systems in particular.

BACKGROUND

Mobile edge computing, also referred to as multi-access edge computing, provides network architectures with computing capabilities at edges of cellular communications networks. For example, mobile edge computing technology can be implemented at cellular base stations and other edge nodes. Relatively early stage mobile edge computing technologies are a feature of fifth generation (5G) cellular networks, and mobile edge computing technologies show promise for further development in 5G and subsequent network deployments.

Mobile edge computing technology enables flexible and rapid deployment of new applications and services for cellular subscribers. Furthermore, by running applications and performing processing closer to cellular subscribers, faster speeds can be achieved and network congestion can be reduced. Mobile edge computing also allows cellular operators to open their radio access networks (RANs) to third parties, such as application developers and content providers.

While mobile edge computing will bring many changes and improvements to cellular communications networks, the potential uses and advantages of mobile edge computing have only begun to be developed. Therefore, there is a need in the industry to take advantage of mobile edge computing to further improve the cellular communications networks in which mobile edge computing will be deployed.

DETAILED DESCRIPTION

One or more embodiments are now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the various embodiments. It is evident, however, that the various embodiments can be practiced without these specific details, and without applying to any particular networked environment or standard.

One or more aspects of the technology described herein are generally directed towards session mapping in multi-access communication networks equipped with mobile edge computing technology, such as 5G and subsequent generation networks. An architecture including a UE and a MEC can use “virtual sessions” to enable service continuity in multi-access environments. A MEC can terminate a main session between the core and the MEC, and based on the services and the states of the access network in the multi-access environment, the MEC can dynamically route/bridge the main session to one or more virtual sessions in the multiple access technologies environment, thereby providing seamless session continuity in the operators' network.

Mobile operators need competitive solutions to provide end users with a seamless experience of mobility across many different access technologies including third generation partnership project (3GPP) and non-3GPP technologies, such as Wi-Fi and satellite. For example, a user watching a video at a coffee shop using Wi-Fi should be able continue the video experience when leaving the Wi-Fi area and moving to an LTE/5G network, or to an area with satellite service. Similarly, a user watching a video started in an LTE/5G service area should be able continue the video experience when walking into a coffee shop and connecting to Wi-Fi, or when moving into an area of satellite service. Mobility management and service continuity across many access technologies is very important.

FIG. 1 illustrates a non-limiting example of a wireless communication system 100 in accordance with various aspects and embodiments of the subject disclosure. In one or more embodiments, system 100 can comprise one or more user equipment UEs 102 ₁, 102 ₂, referred to collectively as UEs 102, a network node 104, and communication service provider network(s) 106.

The non-limiting term “user equipment” can refer to any type of device that can communicate with a network node 104 in a cellular or mobile communication system 100. UEs 102 can have one or more antenna panels having vertical and horizontal elements. Examples of UEs 102 comprise target devices, device to device (D2D) UEs, machine type UEs or UEs capable of machine to machine (M2M) communications, personal digital assistants (PDAs), tablets, mobile terminals, smart phones, laptop mounted equipment (LME), universal serial bus (USB) dongles enabled for mobile communications, computers having mobile capabilities, mobile devices such as cellular phones, laptops having laptop embedded equipment (LEE, such as a mobile broadband adapter), tablet computers having mobile broadband adapters, wearable devices, virtual reality (VR) devices, heads-up display (HUD) devices, smart cars, machine-type communication (MTC) devices, and the like. UEs 102 can also comprise IOT devices that communicate wirelessly.

In various embodiments, system 100 comprises communication service provider network(s) 106 serviced by one or more wireless communication network providers. Communication service provider network(s) 106 can include a “core network”. In example embodiments, UEs 102 can be communicatively coupled to the communication service provider network(s) 106 via network node 104. The network node 104 (e.g., network node device) can communicate with UEs 102, thus providing connectivity between the UEs 102 and the wider cellular network. The UEs 102 can send transmission type recommendation data to the network node 104. The transmission type recommendation data can comprise a recommendation to transmit data via a closed loop MIMO mode and/or a rank-1 precoder mode.

A network node 104 can have a cabinet and other protected enclosures, computing devices, an antenna mast, and multiple antennas for performing various transmission operations (e.g., MIMO operations). Network node 104 can comprise one or more base station devices which implement features of the network node 104. Network nodes can serve several cells, also called sectors, depending on the configuration and type of antenna. In example embodiments, UEs 102 can send and/or receive communication data via a wireless link to the network node 104. The dashed arrow lines from the network node 104 to the UEs 102 represent downlink (DL) communications and the solid arrow lines from the UEs 102 to the network node 104 represents an uplink (UL) communications.

Communication service provider networks 106 can facilitate providing wireless communication services to UEs 102 via the network node 104 and/or various additional network devices (not shown) included in the one or more communication service provider networks 106. The one or more communication service provider networks 106 can include various types of disparate networks, including but not limited to: cellular networks, femto networks, picocell networks, microcell networks, internet protocol (IP) networks Wi-Fi service networks, broadband service network, enterprise networks, cloud based networks, millimeter wave networks and the like. For example, in at least one implementation, system 100 can be or include a large scale wireless communication network that spans various geographic areas. According to this implementation, the one or more communication service provider networks 106 can be or include the wireless communication network and/or various additional devices and components of the wireless communication network (e.g., additional network devices and cell, additional UEs, network server devices, etc.).

The network node 104 can be connected to the one or more communication service provider networks 106 via one or more backhaul links 108. For example, the one or more backhaul links 108 can comprise wired link components, such as a T1/E1 phone line, a digital subscriber line (DSL) (e.g., either synchronous or asynchronous), an asymmetric DSL (ADSL), an optical fiber backbone, a coaxial cable, and the like. The one or more backhaul links 108 can also include wireless link components, such as but not limited to, line-of-sight (LOS) or non-LOS links which can include terrestrial air-interfaces or deep space links (e.g., satellite communication links for navigation). In an embodiment, network node 104 can be part of an integrated access and backhaul network. This may allow easier deployment of a dense network of self-backhauled 5G cells in a more integrated manner by building upon many of the control and data channels/procedures defined for providing access to UEs.

Wireless communication system 100 can employ various cellular systems, technologies, and modulation modes to facilitate wireless radio communications between devices (e.g., the UE 102 and the network node 104). While example embodiments might be described for 5G new radio (NR) systems, the embodiments can be applicable to any radio access technology (RAT) or multi-RAT system where the UE operates using multiple carriers e.g., LTE FDD/TDD, GSM/GERAN, CDMA2000 etc.

For example, system 100 can operate in accordance with global system for mobile communications (GSM), universal mobile telecommunications service (UMTS), long term evolution (LTE), LTE frequency division duplexing (LTE FDD, LTE time division duplexing (TDD), high speed packet access (HSPA), code division multiple access (CDMA), wideband CDMA (WCMDA), CDMA2000, time division multiple access (TDMA), frequency division multiple access (FDMA), multi-carrier code division multiple access (MC-CDMA), single-carrier code division multiple access (SC-CDMA), single-carrier FDMA (SC-FDMA), orthogonal frequency division multiplexing (OFDM), discrete Fourier transform spread OFDM (DFT-spread OFDM) single carrier FDMA (SC-FDMA), Filter bank based multi-carrier (FBMC), zero tail DFT-spread-OFDM (ZT DFT-s-OFDM), generalized frequency division multiplexing (GFDM), fixed mobile convergence (FMC), universal fixed mobile convergence (UFMC), unique word OFDM (UW-OFDM), unique word DFT-spread OFDM (UW DFT-Spread-OFDM), cyclic prefix OFDM CP-OFDM, resource-block-filtered OFDM, Wi Fi, WLAN, WiMax, and the like. However, various features and functionalities of system 100 are particularly described wherein the devices (e.g., the UEs 102 and the network device 104) of system 100 are configured to communicate wireless signals using one or more multi carrier modulation schemes, wherein data symbols can be transmitted simultaneously over multiple frequency subcarriers (e.g., OFDM, CP-OFDM, DFT-spread OFMD, UFMC, FMBC, etc.). The embodiments are applicable to single carrier as well as to multicarrier (MC) or carrier aggregation (CA) operation of the UE. The term carrier aggregation (CA) is also called (e.g., interchangeably called) “multi-carrier system”, “multi-cell operation”, “multi-carrier operation”, “multi-carrier” transmission and/or reception. Note that some embodiments are also applicable for Multi RAB (radio bearers) on some carriers (that is data plus speech is simultaneously scheduled).

In various embodiments, system 100 can be configured to provide and employ 5G or subsequent generation wireless networking features and functionalities. 5G wireless communication networks are expected to fulfill the demand of exponentially increasing data traffic and to allow people and machines to enjoy gigabit data rates with virtually zero latency. Compared to 4G, 5G supports more diverse traffic scenarios. For example, in addition to the various types of data communication between conventional UEs (e.g., phones, smartphones, tablets, PCs, televisions, internet enabled televisions, etc.) supported by 4G networks, 5G networks can be employed to support data communication between smart cars in association with driverless car environments, as well as machine type communications (MTCs). Considering the drastic different communication needs of these different traffic scenarios, the ability to dynamically configure waveform parameters based on traffic scenarios while retaining the benefits of multi carrier modulation schemes (e.g., OFDM and related schemes) can provide a significant contribution to the high speed/capacity and low latency demands of 5G networks. With waveforms that split the bandwidth into several sub-bands, different types of services can be accommodated in different sub-bands with the most suitable waveform and numerology, leading to an improved spectrum utilization for 5G networks.

To meet the demand for data centric applications, features of proposed 5G networks can comprise: increased peak bit rate (e.g., 20 Gbps), larger data volume per unit area (e.g., high system spectral efficiency—for example about 3.5 times that of spectral efficiency of long term evolution (LTE) systems), high capacity that allows more device connectivity both concurrently and instantaneously, lower battery/power consumption (which reduces energy and consumption costs), better connectivity regardless of the geographic region in which a user is located, a larger numbers of devices, lower infrastructural development costs, and higher reliability of the communications. Thus, 5G networks can allow for: data rates of several tens of megabits per second should be supported for tens of thousands of users, 1 gigabit per second to be offered simultaneously to tens of workers on the same office floor, for example; several hundreds of thousands of simultaneous connections to be supported for massive sensor deployments; improved coverage, enhanced signaling efficiency; reduced latency compared to LTE.

The upcoming 5G access network can utilize higher frequencies (e.g., >6 GHz) to aid in increasing capacity. Currently, much of the millimeter wave (mmWave) spectrum, the band of spectrum between 30 GHz and 300 GHz is underutilized. The millimeter waves have shorter wavelengths that range from 10 millimeters to 1 millimeter, and these mmWave signals experience severe path loss, penetration loss, and fading. However, the shorter wavelength at mmWave frequencies also allows more antennas to be packed in the same physical dimension, which allows for large-scale spatial multiplexing and highly directional beamforming.

Performance can be improved if both the transmitter and the receiver are equipped with multiple antennas. Multi-antenna techniques can significantly increase the data rates and reliability of a wireless communication system. The use of multiple input multiple output (MIMO) techniques, which was introduced in the 3GPP and has been in use (including with LTE), is a multi-antenna technique that can improve the spectral efficiency of transmissions, thereby significantly boosting the overall data carrying capacity of wireless systems. The use of MIMO techniques can improve mmWave communications and has been widely recognized a potentially important component for access networks operating in higher frequencies. MIMO can be used for achieving diversity gain, spatial multiplexing gain and beamforming gain. For these reasons, MIMO systems are an important part of the 3rd and 4th generation wireless systems and are planned for use in 5G systems.

FIG. 2 provides an example architecture including a core network computing device, a MEC, multiple access network computing devices, and a UE, in accordance with various aspects and embodiments of the subject disclosure. The example architecture 200 includes a MEC 206 in a main session 204 with a core network computing device 202, and the MEC 206 in multiple virtual sessions 212, 214, and 216 with multiple access network computing devices 222, 224, and 226. In the illustrated example, one of the virtual sessions 216 is used by a UE 230.

In an example, the UE 230 can connect to any appropriate access network computing devices 222, 224, and 226, thereby communicating via any appropriate virtual session of the virtual sessions 212, 214, and 216. In FIG. 2, the UE 230 is illustrated as connected to access network computing device 226, thereby communicating via virtual session 216. As UE 230 moves from one location to another, as indicated by the horizontal arrows from UE 230, UE 230 can connect to other access network computing devices via other virtual sessions.

MEC 206 can comprise a server which provide cloud computing services at an edge of a communications network. MEC 206 can bridge between main session 204 and the virtual session(s) to which the UE 230 is connected. For example, in FIG. 2, MEC 206 establishes a bridge 208 between main session 204 and virtual session 216. If UE 230 moves to a next virtual session, such as virtual session 214, MEC 206 can establish a bridge between main session 204 and the next virtual session 214.

In FIG. 2, the different access network computing devices 222, 224, and 226 can represent different access technologies, such as cellular, Wi-Fi, satellite, and so on. These different access technologies can use different session information. By discovering access network computing devices 222, 224, and 226 and establishing virtual sessions 212, 214, and 216 in advance of UE 230 communicating via access network computing devices 222, 224, and 226, the MEC 206 can enhance the speed and continuity of communications with UE 230.

FIG. 3 is a schematic diagram of an example wireless communication system with single session to multiple sessions mapping, in accordance with various aspects and embodiments of the subject disclosure. Wireless communication system 300 comprises elements similar to those introduced in FIG. 1, and elements of FIG. 1 can be supplemented or modified as illustrated in FIG. 3. FIG. 3 includes a core network 302 with core network computing devices 304, an access network 310 and a particular portion 312 of access network 310. The portion 312 includes MEC 316 at network node 314, access network computing devices 318, and UE 330. The MEC 316 can establish a main session 306 with core network 302, namely, with one or more of core network computing devices 304. The MEC 316 can furthermore identify access network computing devices 318 which serve portion 312, and with which MEC 316 can establish virtual sessions 320. Example virtual session 322 is a virtual session of virtual sessions 320 which is currently in use by UE 330. The UE 330 can transition into another virtual session of virtual sessions 320 when advantageous due to location or service requirement changes at UE 330. In some circumstances, the UE 330 can be simultaneously in multiple of virtual sessions 320.

FIG. 4 is a block diagram of an example user equipment (UE) in accordance with various aspects and embodiments of the subject disclosure. UE 330 in FIG. 4 provides a detailed view of aspects of the UE 330 introduced in FIG. 3. In addition to the many other features and functions of a UE described in connection with FIG. 1, UE 330 can comprise a UE operating system (OS) 410 equipped with a connection manager 412, as well as various radios for different access technologies, such as a Wi-Fi radio 422, a satellite (SAT) radio 424, a cellular radio 426, and any other radios, designated as example radio N 428.

In some implementations, the connection manager 412 can consume user plane data 402 and virtual session data 404. Virtual session data 404 can comprise, e.g., IP addresses for virtual sessions established by a MEC 316, and other session information as may be desired at UE 330. In particular, virtual session data 404 can comprise an IP address and other session information for a next virtual session to be entered by UE 330. Virtual session data 404 can originate from MEC 316 and can also be sent to appropriate access network computing devices.

The connection manager 412 can apply the user plane data 402 and virtual session data 404 at a radio of radios 422, 424, 426, and 428, in order to enter a next virtual session according to virtual session data 404. For example, if a current session is a Wi-Fi session using Wi-Fi radio 422, and next virtual session data 404 arrives with session data for a cellular session using cellular radio 426, the connection manager 412 can apply the user plane data 402 and virtual session data 404 at cellular radio 426 to seamlessly transition from the use of Wi-Fi radio 422 to cellular radio 426. Similarly, transitions to and from any of the radios 422, 424, 426, and 428 can be made according to virtual session data 404.

FIG. 5 is a block diagram of an example MEC in accordance with various aspects and embodiments of the subject disclosure. MEC 316 in FIG. 5 provides a detailed view of aspects of the MEC 316 introduced in FIG. 3. In addition to the many other features and functions of a MEC, MEC 316 can comprise session mapping data 522 and a session manager function 500. Session manager function 500 can include a virtual session manager 502, a main session manager 504, a virtual session finder 506, a virtual session selector 508, and a bridge 510. It will be appreciated that FIG. 5 provides one example set of components and an example arrangement thereof, and numerous other components and arrangements can be made by those of skill in the art.

In FIG. 5, the session manager function 500 can record main (core network) session data for a particular UE in session mapping data 522. Virtual session finder 506 can use data 532, e.g., current location data corresponding to the UE of the main session, to identify access network devices that can provide service to the UE at its current location. The session manager function 500 can then establish virtual sessions with the identified access network devices, and the session manager function 500 can record the virtual session data in session mapping data 522, wherein the virtual session data can be mapped or otherwise cross-referenced to the main session data for the particular UE.

In some examples, virtual session selector 508 can use data 534 to select an appropriate virtual session for the UE, from session mapping data 522. Data 534 can include current location data and/or service requirements for the UE. Virtual session selector 508 can optionally select a virtual session that can provide service at the current location of the UE and can meet or exceed service requirements for the UE. Virtual session selector 508 can notify the virtual session manager 502 of any selected virtual session.

In a further aspect, virtual session manager 502 can engage in access network session 512 by facilitating communications by the UE in the virtual session selected by virtual session selector 508. For example, virtual session manager 502 can send, to the UE, virtual session data 404 (see FIG. 4) for a virtual session selected by virtual session selector 508, and virtual session manager 502 can configure bridge 510 to direct communications from a core network session 514 into the access network session 512, and vice versa. Similarly, main session manager 504 can engage in core network session 514 by configuring bridge 510 to direct communications from core network session 514 into the access network session 512, and vice versa.

The components illustrated in FIG. 5 can be designed to operate dynamically as a UE moves from location to location, or as service requirements change for the UE. For example, a displacement of the UE can introduce new data 532 to virtual session finder 506, and the session manager function 500 can record new virtual session data, identified by virtual session finder 506, in session mapping data 522. Session manager function 500 can also establish new virtual sessions corresponding to the newly identified virtual sessions. Similarly, new data 534 can cause virtual session selector 508 to select a next appropriate virtual session for the UE, and the transition to the next session can be handled by virtual session manager 502.

FIG. 6 illustrates example operations of a UE and a MEC, and interactions there between, in accordance with various aspects and embodiments of the subject disclosure. At 601, UE 330 can undergo a change of location or change of service requirements. At 602, in response to the location/service change at UE 330, the MEC 316 can select a next virtual session from session mapping data. At 603, the MEC 316 can send next virtual session data to the UE 330. At 604, in response to receiving the next virtual session data, the UE 330 can select and configure a radio using the received next virtual session data. At 605, the UE 330 has entered the next virtual session, and the UE 330 can engage in session communications using the configured radio. At 606, the MEC 316 can bridge the main session, with the core network, and the next virtual session with an access network device. Operation 606 can continue until a further change of virtual session. At 607, the MEC 316 can identify and establish additional virtual sessions as appropriate for any location and service requirement changes at the UE 330. At 607, the MEC 316 can update session mapping data to include any additional virtual sessions established at operation 606. These additional virtual sessions are now available for possible future use. Any further location or service changes can trigger a return to operation 601 and the operations of FIG. 6 can be repeated as often as appropriate.

FIG. 7 is a flow diagram representing a first set of example operations of a MEC, in accordance with various aspects and embodiments of the subject disclosure. The illustrated blocks can represent actions performed in a method, functional components of a computing device, or instructions implemented in a machine-readable storage medium executable by a processor. While the operations are illustrated in an example sequence, the operations can be eliminated, combined, or re-ordered in some embodiments.

Example operations comprise operation 702, which represents establishing a first network communication session on behalf of a UE, between a MEC and a core network. For example, as illustrated in FIG. 3, MEC 316 can facilitate establishing a first network communication session, namely main session 306, on behalf of UE 330. The first network communication session 306 is between the MEC 316 and a core network computing device of core network computing devices 304. In some embodiments, MEC 316 can be located at and coupled with a base station or other network node 314 of a cellular communications network.

Example operations comprise operation 704, which represents establishing, for the UE, multiple respective network communication sessions between the MEC and multiple respective access network computing devices.

FIG. 10 and the following discussion are intended to provide a brief, general description of a suitable computing environment 1000 in which the various embodiments of the embodiment described herein can be implemented. While the embodiments have been described above in the general context of computer-executable instructions that can run on one or more computers, those skilled in the art will recognize that the embodiments can be also implemented in combination with other program modules and/or as a combination of hardware and software.

Generally, program modules include routines, programs, components, data structures, etc., that perform particular tasks or implement particular abstract data types. Moreover, those skilled in the art will appreciate that the methods can be practiced with other computer system configurations, including single-processor or multiprocessor computer systems, minicomputers, mainframe computers, IoT devices, distributed computing systems, as well as personal computers, hand-held computing devices, microprocessor-based or programmable consumer electronics, and the like, each of which can be operatively coupled to one or more associated devices.

The illustrated embodiments of the embodiments herein can be also practiced in distributed computing environments where certain tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules can be located in both local and remote memory storage devices.

Computing devices typically include a variety of media, which can include computer-readable storage media, machine-readable storage media, and/or communications media, which two terms are used herein differently from one another as follows. Computer-readable storage media or machine-readable storage media can be any available storage media that can be accessed by the computer and includes both volatile and nonvolatile media, removable and non-removable media. By way of example, and not limitation, computer-readable storage media or machine-readable storage media can be implemented in connection with any method or technology for storage of information such as computer-readable or machine-readable instructions, program modules, structured data or unstructured data.

Computer-readable storage media can include, but are not limited to, random access memory (RAM), read only memory (ROM), electrically erasable programmable read only memory (EEPROM), flash memory or other memory technology, compact disk read only memory (CD-ROM), digital versatile disk (DVD), Blu-ray disc (BD) or other optical disk storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, solid state drives or other solid state storage devices, or other tangible and/or non-transitory media which can be used to store desired information. In this regard, the terms “tangible” or “non-transitory” herein as applied to storage, memory or computer-readable media, are to be understood to exclude only propagating transitory signals per se as modifiers and do not relinquish rights to all standard storage, memory or computer-readable media that are not only propagating transitory signals per se.

Computer-readable storage media can be accessed by one or more local or remote computing devices, e.g., via access requests, queries or other data retrieval protocols, for a variety of operations with respect to the information stored by the medium.

Communications media typically embody computer-readable instructions, data structures, program modules or other structured or unstructured data in a data signal such as a modulated data signal, e.g., a carrier wave or other transport mechanism, and includes any information delivery or transport media. The term “modulated data signal” or signals refers to a signal that has one or more of its characteristics set or changed in such a manner as to encode information in one or more signals. By way of example, and not limitation, communication media include wired media, such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared and other wireless media.

With reference again to FIG. 10, the example environment 1000 for implementing various embodiments of the aspects described herein includes a computer 1002, the computer 1002 including a processing unit 1004, a system memory 1006 and a system bus 1008. The system bus 1008 couples system components including, but not limited to, the system memory 1006 to the processing unit 1004. The processing unit 1004 can be any of various commercially available processors. Dual microprocessors and other multi-processor architectures can also be employed as the processing unit 1004.

The system bus 1008 can be any of several types of bus structure that can further interconnect to a memory bus (with or without a memory controller), a peripheral bus, and a local bus using any of a variety of commercially available bus architectures. The system memory 1006 includes ROM 1010 and RAM 1012. A basic input/output system (BIOS) can be stored in a non-volatile memory such as ROM, erasable programmable read only memory (EPROM), EEPROM, which BIOS contains the basic routines that help to transfer information between elements within the computer 1002, such as during startup. The RAM 1012 can also include a high-speed RAM such as static RAM for caching data.

The computer 1002 further includes an internal hard disk drive (HDD) 1014 (e.g., EIDE, SATA), one or more external storage devices 1016 (e.g., a magnetic floppy disk drive (FDD) 1016, a memory stick or flash drive reader, a memory card reader, etc.) and an optical disk drive 1020 (e.g., which can read or write from a CD-ROM disc, a DVD, a BD, etc.). While the internal HDD 1014 is illustrated as located within the computer 1002, the internal HDD 1014 can also be configured for external use in a suitable chassis (not shown). Additionally, while not shown in environment 1000, a solid state drive (SSD) could be used in addition to, or in place of, an HDD 1014. The HDD 1014, external storage device(s) 1016 and optical disk drive 1020 can be connected to the system bus 1008 by an HDD interface 1024, an external storage interface 1026 and an optical drive interface 1028, respectively. The interface 1024 for external drive implementations can include at least one or both of Universal Serial Bus (USB) and Institute of Electrical and Electronics Engineers (IEEE) 1394 interface technologies. Other external drive connection technologies are within contemplation of the embodiments described herein.

The drives and their associated computer-readable storage media provide nonvolatile storage of data, data structures, computer-executable instructions, and so forth. For the computer 1002, the drives and storage media accommodate the storage of any data in a suitable digital format. Although the description of computer-readable storage media above refers to respective types of storage devices, it should be appreciated by those skilled in the art that other types of storage media which are readable by a computer, whether presently existing or developed in the future, could also be used in the example operating environment, and further, that any such storage media can contain computer-executable instructions for performing the methods described herein.

A number of program modules can be stored in the drives and RAM 1012, including an operating system 1030, one or more application programs 1032, other program modules 1034 and program data 1036. All or portions of the operating system, applications, modules, and/or data can also be cached in the RAM 1012. The systems and methods described herein can be implemented utilizing various commercially available operating systems or combinations of operating systems.

Computer 1002 can optionally comprise emulation technologies. For example, a hypervisor (not shown) or other intermediary can emulate a hardware environment for operating system 1030, and the emulated hardware can optionally be different from the hardware illustrated in FIG. 10. In such an embodiment, operating system 1030 can comprise one virtual machine (VM) of multiple VMs hosted at computer 1002. Furthermore, operating system 1030 can provide runtime environments, such as the Java runtime environment or the .NET framework, for applications 1032. Runtime environments are consistent execution environments that allow applications 1032 to run on any operating system that includes the runtime environment. Similarly, operating system 1030 can support containers, and applications 1032 can be in the form of containers, which are lightweight, standalone, executable packages of software that include, e.g., code, runtime, system tools, system libraries and settings for an application.

Further, computer 1002 can be enable with a security module, such as a trusted processing module (TPM). For instance, with a TPM, boot components hash next in time boot components, and wait for a match of results to secured values, before loading a next boot component. This process can take place at any layer in the code execution stack of computer 1002, e.g., applied at the application execution level or at the operating system (OS) kernel level, thereby enabling security at any level of code execution.

A user can enter commands and information into the computer 1002 through one or more wired/wireless input devices, e.g., a keyboard 1038, a touch screen 1040, and a pointing device, such as a mouse 1042. Other input devices (not shown) can include a microphone, an infrared (IR) remote control, a radio frequency (RF) remote control, or other remote control, a joystick, a virtual reality controller and/or virtual reality headset, a game pad, a stylus pen, an image input device, e.g., camera(s), a gesture sensor input device, a vision movement sensor input device, an emotion or facial detection device, a biometric input device, e.g., fingerprint or iris scanner, or the like. These and other input devices are often connected to the processing unit 1004 through an input device interface 1044 that can be coupled to the system bus 1008, but can be connected by other interfaces, such as a parallel port, an IEEE 1394 serial port, a game port, a USB port, an IR interface, a BLUETOOTH® interface, etc.

A monitor 1046 or other type of display device can be also connected to the system bus 1008 via an interface, such as a video adapter 1048. In addition to the monitor 1046, a computer typically includes other peripheral output devices (not shown), such as speakers, printers, etc.

The computer 1002 can operate in a networked environment using logical connections via wired and/or wireless communications to one or more remote computers, such as a remote computer(s) 1050. The remote computer(s) 1050 can be a workstation, a server computer, a router, a personal computer, portable computer, microprocessor-based entertainment appliance, a peer device or other common network node, and typically includes many or all of the elements described relative to the computer 1002, although, for purposes of brevity, only a memory/storage device 1052 is illustrated. The logical connections depicted include wired/wireless connectivity to a local area network (LAN) 1054 and/or larger networks, e.g., a wide area network (WAN) 1056. Such LAN and WAN networking environments are commonplace in offices and companies, and facilitate enterprise-wide computer networks, such as intranets, all of which can connect to a global communications network, e.g., the internet.

When used in a LAN networking environment, the computer 1002 can be connected to the local network 1054 through a wired and/or wireless communication network interface or adapter 1058. The adapter 1058 can facilitate wired or wireless communication to the LAN 1054, which can also include a wireless access point (AP) disposed thereon for communicating with the adapter 1058 in a wireless mode.

When used in a WAN networking environment, the computer 1002 can include a modem 1060 or can be connected to a communications server on the WAN 1056 via other means for establishing communications over the WAN 1056, such as by way of the internet. The modem 1060, which can be internal or external and a wired or wireless device, can be connected to the system bus 1008 via the input device interface 1044. In a networked environment, program modules depicted relative to the computer 1002 or portions thereof, can be stored in the remote memory/storage device 1052. It will be appreciated that the network connections shown are example and other means of establishing a communications link between the computers can be used.

When used in either a LAN or WAN networking environment, the computer 1002 can access cloud storage systems or other network-based storage systems in addition to, or in place of, external storage devices 1016 as described above. Generally, a connection between the computer 1002 and a cloud storage system can be established over a LAN 1054 or WAN 1056 e.g., by the adapter 1058 or modem 1060, respectively. Upon connecting the computer 1002 to an associated cloud storage system, the external storage interface 1026 can, with the aid of the adapter 1058 and/or modem 1060, manage storage provided by the cloud storage system as it would other types of external storage. For instance, the external storage interface 1026 can be configured to provide access to cloud storage sources as if those sources were physically connected to the computer 1002.

The computer 1002 can be operable to communicate with any wireless devices or entities operatively disposed in wireless communication, e.g., a printer, scanner, desktop and/or portable computer, portable data assistant, communications satellite, any piece of equipment or location associated with a wirelessly detectable tag (e.g., a kiosk, news stand, store shelf, etc.), and telephone. This can include Wireless Fidelity (Wi-Fi) and BLUETOOTH® wireless technologies. Thus, the communication can be a predefined structure as with a conventional network or simply an ad hoc communication between at least two devices.
